The many-body wavefunction of a highly entangled quantum system cannot be expressed as the direct product of multiple single-particle states in any basis. Although the entangled wavefunctions can be experimentally characterized in synthetic few-body quantum simulators [1]}, [2]}, [3]}, [4]}, [5]}, e.g. through the Rényi entropy [6]}, [7]}, [8]}, [9]}, [10]} and multi-point correlations [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, its complexity scales exponentially with the system size, while solid-state measurements are restricted to limited observables. Therefore, a tomography of electronic wavefunctions in a sizeable quantum material is impractical [19]}, [20]}, [21]}, [22]}.
